Fill in the blanks (underlined) on the following sentences to describe how the sliding filament model works.
My brain sends an action potential along the _____________________________ _____________________________ until it synapses with a muscle cell in my arm. receptors in the muscle cell are _____________________________ _____________________________ _____________________________, so when the motor neuron releases
_____________________________ into the synapse, the channels open up and create a rush of sodium into the cell, which if it's strong enough will cause nearby voltage-gated sodium channels to open as well. the action potential zips along a muscle cell's membrane, called the _____________________________, which has lots of tubes that run deep inside the cell, called _____________________________. When an action potential travels down one t-tubules it eventually triggers the voltage sensitive proteins that are linked those calcium channels on the cell’s _____________________________ _____________________________. when the sarcoplasmic reticulum channels are thrown open, the calcium stored inside rushes into the rest of the cell. The protein _____________________________ loves to bind with calcium, which changes its shape. The calcium latches onto the troponin and causes it to pull _____________________________ away from the sites on the _____________________________ strands that the _____________________________ wants to attach to. Only myosin heads that have a molecule of _____________________________ broken down into
_____________________________ and leftover _____________________________ can bind to newly exposed sites. when the myosin finally binds to actin, the myosin releases all of the stored energy and changes _____________________________. By changing shape it pulls on the actin strand and in the process it _____________________________ the whole sarcomere, and _____________________________ the muscle. Once the _____________________________ is spent, the myosin has no use for the ADP in the phosphate, so they unbind. The unbinding causes a small change in shape which allows a fresh ATP to bind to the myosin head. This _____________________________ causes another shape change and causes the _____________________________ to release the _____________________________. Meanwhile, the _____________________________ pumps are working hard to restock the calcium and the sarcoplasmic reticulum, so they start grabbing the _____________________________ that is floating around, causing calcium to unbind from _____________________________. When it un binds, the shape change puts the _____________________________ back into place.

The words which completes the passage about how the sliding filament model works are:

The sliding filament model can be defined as a theory which states that the mechanism of muscle contraction occurs when actin and myosin filaments of striated muscle (muscle proteins) slide past each other, so as to generate movement in the body of a living organism.

Basically, the human brain sends an action potential along the motor neurons until the action potential synapses with a muscle cell in the body part of a living organism such as arm, leg, etc.

This 52 year-old woman has been complaining of diffuse pelvic pain with urinary bladder spasms since cystoscopy 10 days ago at which time marked cystitis was noted.

Past History: The patient reports episodes of nocturia three to four times a night, urinary frequency, urinary urgency, and epigastric discomfort. She has a history of polyuria, hematuria, and urinary incontinence.

Impression: Urinary incontinence is caused by cystitis and is temporary in nature.

Plan:

This 50-year-old male patient, carpenter, stated that he has lost approximately 40 lbs since his last examination.

History: Patient says he has had no dysphagia or postprandial distress, and there is no report of diarrhea, nausea, emesis, hematemesis, or constipation. Patient has had a history or regional enteritis, appendicitis, and colon bleeding. The regional enteritis resulted in a ileosotmy with appendectomy about 6 months ago.

Assessment: His sigmoidoscopy using a 10-cm scope showed no evidence of bleeding at the anorectal area. A 35-cm scope was then inserted to a level of 13 cm. At this point, angulation prevented further passage of the scope. No abnormalities had been encountered, but dark blood was noted at that level.

Impression: My impression is that the rectal bleeding could be caused by a polyp, ulcerative colitis, or colorectal carcioma.

Plan: Patient has been advised to schedule a colonoscopy next week and to come to the emergency department if symptoms worsen.
